(1) YHWH said to Moses and Aaron in the land of Egypt: (2) This month shall mark for you the beginning of the months; it shall be the first of the months of the year for you. (3) Speak to the community leadership of Israel and say that on the tenth of this month each of them shall take a lamb to a family, a lamb to a household. (4) But if the household is too small for a lamb, let it share one with a neighbor who dwells nearby, in proportion to the number of persons: you shall contribute for the lamb according to what each household will eat. (5) Your lamb shall be without blemish, a yearling male; you may take it from the sheep or from the goats. (6) You shall keep watch over it until the fourteenth day of this month; and all the assembled congregation of the Israelites shall slaughter it at twilight. (7) They shall take some of the blood and put it on the two doorposts and the lintel of the houses in which they are to eat it. (8) They shall eat the flesh that same night; they shall eat it roasted over the fire, with unleavened bread and with bitter herbs. (9) Do not eat any of it raw, or cooked in any way with water, but roasted—head, legs, and entrails—over the fire. (10) You shall not leave any of it over until morning; if any of it is left until morning, you shall burn it. (11) This is how you shall eat it: your loins girded, your sandals on your feet, and your staff in your hand; and you shall eat it hurriedly: it is a passover offering to YHWH. (12) For that night I will go through the land of Egypt and strike down every [male] first-born in the land of Egypt, both human and beast; and I will mete out punishments to all the gods of Egypt, I YHWH (13) And the blood on the houses where you are staying shall be a sign for you: when I see the blood I will pass over you, so that no plague will destroy you when I strike the land of Egypt. (14) This day shall be to you one of remembrance: you shall celebrate it as a festival to YHWH throughout the ages; you shall celebrate it as an institution for all time.
(ה) מַה בֵּין פֶּסַח מִצְרַיִם לְפֶסַח דּוֹרוֹת, פֶּסַח מִצְרַיִם מִקָּחוֹ מִבֶּעָשׂוֹר,
וְטָעוּן הַזָּאָה בַאֲגֻדַּת אֵזוֹב עַל הַמַּשְׁקוֹף וְעַל שְׁתֵּי מְזוּזוֹת,
וְנֶאֱכָל בְּחִפָּזוֹן בְּלַיְלָה אֶחָד, וּפֶסַח דּוֹרוֹת נוֹהֵג כָּל שִׁבְעָה:
(5) What are the differences between the Pesach of Egypt and the Pesach of the generations?
The Pesach of Egypt had to be taken from the tenth [of the month of Nisan]
and required the the sprinkling of blood with a bundle of hyssop on the lintel and the two doorposts,
and it was eaten with haste on one night while Pesach of the generations is observed for seven days.
[The rabbis] were familiar with Greek customs and their banquet manners, that when the festivities would reach their peak, they would burst into others' homes to force them to join in the continuing party, and they called this epikomazein. The Mishna warns that one does not conclude the Passover meal with an afikoman-epikomazein, and this is the interpretation of the Babylonian and Eretz Yisraeli Talmud.
--S. Leiberman, as cited in The Schechter Haggadah, 261.
טיפש מה אומר: מה זאת
אף את למדו הלכות הפסח שאין מפטירין אחר הפסח אפיקומן שלא יהא עומד מחבורה זו ונכנס לחבורה אחרת.
Palestinian Talmud Pesachim 10:4, 37d
The stupid child, what does he say: What is this?
You should teach him the laws of Pesach, that one does not conclude with an afikoman after Pesach, so that he won't arise from this gathering and go to another gathering.
(יא) אין מפטירין אחר הפסח אפיקומן, כגון אגוזין, תמרים, וקליות. חייב אדם לעסוק בהלכות הפסח כל הלילה, אפלו בינו לבין בנו, אפלו בינו לבין עצמו, אפלו בינו לבין תלמידו.
(יב) מעשה ברבן גמליאל וזקנים שהיו מסובין בבית ביתוס בן זונין בלוד, והיו עסוקין בהלכות הפסח כל הלילה עד קרות הגבר, הגביהו מלפניהן, ונועדו והלכו להן לבית המדרש.
One may not conclude after the Pesach with an afikoman, like nuts and dates and parched corn. One must engage in the laws of Pesach all night, even if it is just between one and one's son, even if it just one by oneself, even if it is just between one and one's student.
It happened once that Rabban Gamliel and the elders were reclining in the house of Beitos ben Zunin in Lud, and they were engaged with the laws of Pesach all night until the call of the rooster. They removed [the tables before them] and they got up and went to the house of study.
מַעֲשֶׂה בְּרַבִּי אֱלִיעֶזֶר וְרַבִּי יְהוֹשֻׁעַ וְרַבִּי אֶלְעָזָר בֶּן-עֲזַרְיָה וְרַבִּי עֲקִיבָא וְרַבִּי טַרְפוֹן שֶׁהָיוּ מְסֻבִּין בִּבְנֵי-בְרַק וְהָיוּ מְסַפְּרִים בִּיצִיאַת מִצְרַיִם כָּל-אוֹתוֹ הַלַּיְלָה, עַד שֶׁבָּאוּ תַלְמִידֵיהֶם וְאָמְרוּ לָהֶם רַבּוֹתֵינוּ הִגִּיעַ זְמַן קְרִיאַת שְׁמַע שֶׁל שַׁחֲרִית.
It happened once that Rabbi Eliezer, Rabbi Yehoshua, Rabbi Elazar ben Azariah, Rabbi Akiva and Rabbi Tarfon were reclining in Bnei Brak and were telling the story of the exodus from Egypt that whole night, until their students came and said to them, "The time for reciting the morning Shema has arrived."
